The swing of the speed reducing plate A12, the speed reducing plate B15, the speed reducing plate C18 and the speed reducing plate D20 drives the plate spring 63 for resetting to deform and store energy. The group of speed reducing plates A12 and the group of speed reducing plates B15 in each n-shaped groove 9 do not form effective shielding and speed reduction on the air flow entering from the ventilation grille 4 due to synchronous swing, the two speed reducing plates C18 and the two speed reducing plates D20 in the top of the n-shaped groove 9 do not form effective shielding and speed reduction on the air flow entering from the two branches of the n-shaped groove 9 due to synchronous swing, and the original air in the n-shaped groove 9 is completely replaced by the high-speed air flow entering from the outside in a new environment.
Then, the pressing force on the trigger lever 24 is removed, the trigger lever 24 is reset instantly under the reset action of the spring A25 and drives the four trigger pins 22 to release the pressing on the four pull ropes A14 through the synchronous frame 23, the speed reducing plate A12, the speed reducing plate B15, the speed reducing plate C18 and the speed reducing plate D20 are swung back instantly under the reset action of the plate spring 63 to reset and form effective shielding and speed reduction on the air flow entering from the ventilation grille 4 again, meanwhile, the protection of air entering the top of the n-shaped groove 9 and fully and stably contacting the monitoring module is guaranteed, so that the detection module 10 fully and effectively detects the air which is almost in a static state, and the detection precision of the detector 1 on the air components in the new environment is improved.
When the detector 1 needs to be fixed on a rough wall surface by suction, the smooth circular plate 61 matched with the suction disc B31 is firstly installed at the position where the detector 1 is sucked on the front surface by gluing. Then, the suction cup B31 is aligned with the circular plate 61 and the suction cup a28 is pressed against the wall surface, so that the silicone sealing ring 29 at the edge of the suction cup a28 is in sufficient contact with the rough wall surface and a sealed space is formed in the suction cup a28, and at the same time, the suction cup B31 is pressed against the circular plate 61 by the suction cup a28 through the pressing block 32 and a sealed space is formed.
Then, the L-shaped lock lever 43 is toggled, the lock lever 43 drives the rack B42 hinged thereto to slide outward of the chute B6 at the lower end of the detector 1, the rack B42 drives the ring sleeve 33 to retract into the chute C7 at the back of the detector 1 for a certain distance through the gear B41, the gear a40 and the rack a39, the ring sleeve 33 drives the sliding plug 35, the screw 37 and the gear C44 to move synchronously, the ring sleeve 33 also drives the sucker a28 to retract into the bowl 27, and the sucker a28 drives the sucker B31 to retract synchronously through the connecting rod 30. During the contraction of the suction cup a28 and the suction cup B31 along with the movement of the ring sleeve 33, a vacuum-like operation occurs in the sealed space between the suction cup a28 and the suction cup B31, so that the suction cup a28 is tightly attached to the rough wall surface, and the suction cup B31 is tightly attached to the circular plate 61. The matching of the suction disc B31 and the circular plate 61 can effectively assist the suction disc A28 to be adsorbed and fixed on a rough wall surface, and the reliability of adsorption and fixation on the wall surface of the invention is improved.
When the lock lever 43 is shifted to the limit, the distance by which the rack B42 slides out of the chute B6 is locked, and the suction of the suction cup a28 to the rough wall surface and the suction of the suction cup B31 to the circular plate 61 are maintained.
After the detector 1 is fixed on a rough wall surface by the suction cup A28 and the suction cup B31 in an adsorption manner, the pull rope C57 is pulled, the pull rope C57 drives the winding wheel 55 to rotate for a certain angle, the one-way clutch 54 plays an overrunning role, and the volute spring B58 is compressed to store energy.
When the energy stored in the scroll spring B58 is sufficient, the tension of the pull rope C57 is removed, and the winding wheel 55 intends to return under the return action of the scroll spring B58, but at this time, the one-way clutch 54 performs the one-way driving action. The sliding plug 35 cannot axially contract towards the inner part of the ring sleeve 33 because the inner space of the suction cup A28 is in a sealed vacuum state, so that the screw rod 37 in threaded fit with the sliding plug 35 is prevented from rotating, and the screw rod 37 prevents the winding wheel 55 from winding the pulling rope C57 back through the gear C44, the gear D45, the gear E46, the gear F47 and the one-way clutch 54 and keeps the energy storage state of the volute spring B58.
When the sucker A28 adsorbed on the rough wall surface leaks air due to the sealing ring 29 and the wall surface, the suction force of the sliding plug 35 in the vacuum environment in the sucker A28 is reduced, the stress balance at the two ends of the sliding plug 35 is broken, the energy-storing volute spring B58 drives the screw 37 to rotate relative to the ring sleeve 33 through the winding wheel 55, the one-way clutch 54, the rotating shaft 48, the gear F47, the gear E46, the gear D45 and the gear C44, the volute spring A38 starts to store energy, the screw 37 drives the sliding plug 35 in threaded fit with the screw to axially contract towards the inside of the ring sleeve 33 and vacuumize the space in the sucker A28, and therefore the sucker A28 extrudes the sucker A28 and the silica gel rubber ring on the sucker A28 towards the wall surface under the action of the external atmospheric pressure, and the sucker A28 is adsorbed on the rough wall surface again. As long as sucking disc A28 adsorbs for a long time and appears leaking gas, the volute spring B58 of energy storage all can drive sliding plug 35 through a series of transmissions and carry out vacuum pumping operation again in the sucking disc A28 that takes place to leak gas for sucking disc A28 can adsorb in the coarse wall surface lastingly, guarantees the fixed persistence and more reliable of detector 1 on the coarse wall surface, and can not provide power for sliding plug 35 to contract in the ring cover 33 again until the energy storage of volute spring B58 finishes.
When the detector 1 needs to be taken down from the wall surface, the locking rod 43 is only required to be pulled back to unlock the rack B42, the unlocked rack B42 moves out of the chute C7 at the back of the detector 1 through a series of driving rings 33, and the rings 33 drive the suckers a28 to reset, so that the adsorbability on the wall surface is lost. The suction cup B31 is easily pulled out from the wall surface due to interaction with the circular plate 61 adhered to the wall surface.
Then, the pull rope B53 is pulled, and the pull rope B53 brings the slide base 49 and all the components on the slide base 49 into synchronous motion, and the spring B52 is further compressed. The gear F47 is disengaged from the gear E46, and the screw 37 rotates reversely under the reset action of the volute spring A38 and drives the sliding plug 35 to axially slide back and reset in the ring sleeve 33. With the disengagement of the gear E46 and the gear F47, the spiral spring B58 drives the gear F47 to idle through the winding wheel 55, the one-way clutch 54 and the drill shaft until the energy release of the spiral spring B58 is finished.
When the sliding plug 35 is reset and the energy of the volute spring B58 is released, the pulling force on the pulling rope B53 is removed, the slide seat 49 drives all the components on the slide seat to slide back under the reset action of the spring B52, and the gear E46 is re-meshed with the gear F47.
In summary, the beneficial effects of the invention are as follows: according to the invention, the speed reducing mechanism 11 arranged in the n grooves of the detector 1 is used for effectively reducing the speed of high-speed air flow in the environment entering the detector 1 and keeping the air entering the n grooves stable, so that the detection module 10 is beneficial to accurately detecting the air remained in the detector. When the speed reducing mechanism 11 of the invention needs to detect the new environment air, the speed reducing mechanism 11 is firstly opened to enable the air in the environment to fully and quickly enter the n grooves and discharge the original air in the environment, thereby ensuring the accurate detection of the internal detection module 10 on the air in the new environment.
<xnotran> , A28 29 A28 62, 62 A28 A28 , A28 62 . </xnotran> According to the invention, the suction cup B31 can assist the suction cup A28 to adsorb and fix the detector 1 on the rough wall 62 after the auxiliary suction cup A28 and the suction cup B31 are fixed on the wall 62 by the detector 1, so that double insurance is added. Simultaneously, sucking disc B31 provides effectual impetus for sucking disc A28 evacuation during the automatic operation of evacuation after sucking disc A28 became invalid to guarantee that sucking disc A28 can carry out effectual automatic evacuation operation, and then guarantee that sucking disc A28 adsorbs detector 1 and be fixed in the reliability of wall body 62.
